what the hell, is this real life where people talk to each other properly? The story feels pretty much completed though, i wonder what more could there be, it is tagged as ongoing.
I always see people say that when pertaining to drama with a story that has misunderstandings, well you do know that if all these characters were to just "talk it out" then most stories would be boring as hell. This is not real life. Stop trying to apply your real life logic to fiction.
...I think that person meant that he/she was surprised (in a good way) the characters talked it out properly like most ppl in real life would, as opposed to what they normally would have done in manga/fiction.
Rather than applying his/her real life logic to fiction like you said, the story already did that and he/she was making a joke that this manga was realistic in that aspect ("is this real life where people talk to each other properly?"). Just a misunderstanding but it makes more sense to read the comment this way because the manga clearly worked out without excessive miscommunication, avoidance, etc.
